ABSTRACT MOLD CLOSING UNIT A mold closing unit for use in an injection molding machine for processing plastic materials for removal of moldings is provided with a device for actuating at least two first identical parts of an injection mold, which are transferred alternately into the space between the mold carriers of the mold closing unit on a guideway that runs transversally with respect to the closing direction for creation of an injection mold. Since all parts of the injection mold together with their corresponding swivel arms constitute a single oscillating crank with multiple arms, which transfers the first parts of the injection mold substantially in the parting plane of the mold closing unit, and since the position of the oscillating crank in the mold stressing chamber is determined by the mold closure itself, at least one of the first part of an injection mold being located outside the injection mold is fixed in a precise position that can be repeated for each injection cycle, the moldings can be handed over to a removal device and shorter production times with a faster ejection of moldings is obtained.
